Kim Jong Un threatens to 'tame' Trump

"These are what constitute the gravest threat to the worldwide peace and security today". The North Korean leader earlier labelled Trump "mentally deranged" and a "dotard" after Trump threatened to destroy his country.

North Korea depends on China for nearly all its oil and gas but estimates of its consumption are low, leaving it unclear how Beijing's new limit will affect them.

Elleman said the missile of choice in a North Korean atmospheric H-bomb test likely would be its longest-range ballistic missile, known as the Hwasong-14, which apparently has the capability of reaching the USA mainland, or the intermediate-range Hwasong-12.

"This mission is a demonstration of U.S. resolve and a clear message that the President has many military options to defeat any threat", Pentagon spokeswoman Dana White said in a statement.

North Korea has abundant coal but depends nearly entirely on imports for oil and gas.

"We are prepared to use the full range of military capabilities to defend the USA homeland and our allies".

TONIGHT: Capping off a wild week at the #UNGA, Stephen wades into the war of words between President Trump and Kim Jong Un.

In a speech to the UN General Assembly on Tuesday, Trump warned Kim that the United States, if threatened, would "totally destroy" his country of 26 million people.

UN Secretary-General António Guterres met with Ri on Saturday.

The news - which is sure to inflame tensions with Pyongyang - came as the US Air Force carried out practice bombing raids in a show of force over the Korean Peninsula.

"You come to my house and insult my president", he said, "who granted, I think isn't fit to sit in a White Castle, let alone a White House".

Washington on Thursday authorized a tough new raft of sanctions in the latest effort to tighten the screws on Pyongyang over its banned weapons programs, following its sixth nuclear test - the largest yet - and the firing of two missiles over Japan in recent weeks.

"But Kim Jong-Un and the Iranians have never seen anyone talk back to them in these terms". In an unprecedented personal statement, Kim said Trump would "pay dearly" for his speech, which he labelled "unprecedented rude nonsense".

Kim said Trump's remarks "have convinced me, rather than frightening or stopping me, that the path I chose is correct and that it is the one I have to follow to the last".

"I will make the man holding the prerogative of the supreme command in the United States pay dearly for his speech".

But it also fears the consequences if the regime collapses, such as an exodus of refugees or a US-allied, reunited Korea on its border.

China's official Xinhua News Agency said the country's seismic service detected a magnitude 3.4 quake in North Korea and saw the likely cause as an explosion.

Pyongyang later said it had tested a hydrogen bomb that could be fitted onto a missile - an assertion that no foreign government has so far confirmed.

A ban on textile imports from the North will go into effect immediately, the statement said. Those threats have been met by harsh United Nations sanctions, and Trump this week rolled out a new set of rules aimed at penalizing individuals and entities that do business with North Korea.

China's official Xinhua news agency said the epicentre was roughly at the same place as a similar shallow natural disaster on September 3, which turned out to be caused by North Korea's sixth and largest nuclear test.

Analysts were working to determine whether the tremors detected near the Punggye-ri nuclear site were natural or man-made.
